ABSTRACT: The article deals with the mechanization of the maintenance
works of the Na,",in (open hearth) furnaces. Special repair
trusts (YuzlidomnRremont trust and other%, developed work
methods which considerably cut dorn the idle time of fu--naces
by introducing special tnols and installations to speed up
the repair work; conveyer belts were in3talled in the modern
plants for thp evacuation of slag and broken brick and for
the transportation to the furnaces cf new material necessary
for maintenance work. Mechanizei methods of repair are sti*_1
insufficiently developed; many operations are still done by
manuai labor; many repair shop.-- must be reorganized and

ABSTRACT: The IR absorption spectra oi 13 t-hromit-as of ram earth ele~aants were taken
usiTC a UR-10 spectrophotometer. Chromite samples were prepared by two techniques:
by growing single crystals frm a melt cortaining 'PbO+PbF2 mixed selvent, the melt was
beld at 13600C for 4 hours wisereupon the melt temp~arature m-w reduced from 136010C to
10000C at a rate of 10-300 per hour. Under the se.-,ond method, mixtures of the claro-
alum mide wEm fused with a rare earth element oxide at 20006C for 15 minutes in an
anon atmosphere. Individual chromite phases were examined by petrographic and x-ray
analyses and the chromite compositions were confimed by chemical analysis. The IR i
spectra of chromites of the cerium subgroup elements are sham In figur* I. The IR

ABSTRAC7: The authors describe an investigation of the effect of saturating liquids
upon the propagation velocity of elastic longitudinal waves in samples of sedimentary
rocks exposed to amnidirectional pressures up to 1500 kg/=2 and terperatures up to
1500C. Mile it is known that variations in the physical properties of min3rals (caus-
ed by the saturating liquids) can be used for the detection of oil deposits, th
very little da-ta available an the effect of these liquids ors the physical para or* is

of sedimentary rocks. The expbriments were basse on measurements of the propagation
velocity of ultrasonic vibrations through various samples cAP clay and sandstone under
accurately controlled -anditions of prese-a-rre and temperature, both in presence and Ja

cial chamber vats constructed, designed to vithstand pressures up to 5000 kg/CM2 and
teriperatures up to 3000C. This chamber was equipped with a heating element, an oil
pump to generate amnidirectional pressure on the sample, an ultrasonic transducer ard
receiver, as well as various temperature and pressure gages for measuring and control-
ling -the internal environment. The authors measured the variations of sound propaga-
tion (at about 100 XHz) caused by changes in temperature end pressure in dry and li-
quid saturated rock samples. Dry samples of sandstone exhibited nonlinear change of
propagation velocity with respect to amnidirectional prear-ure. The changes were much
less pronounced for dry clay. In the liquid-saturated sam.1les, the absolute "loci"-y
was higher (up to 500 a/sec) due to greater acoustical coupling area but the changea
in-velocity for sandstone were now similar to those in clay, which differed only
slightly from the dry sample. The higher degree of velocity variation in dry sandstone
cari be attributed to more rapid closure of pores under ambient nressure than in clay.
The increase in temperature causes reduction in propagation vel;city in both dry and
liquid saturated samples. Tt& following conclusions are made based on the results of
rhese experiments: 1. In dry samples, the changes in propagation velocity of longitu-
dinal waves depend upon lithological composition and the nature 6f porosity. In clays.
2
such cho-4es are gradual and in sandstone there is an abrupt change at 500 kg/cm
with a subsequent decrease in the gradient. 2. The velocity chw4ges witi. respect to
pressure are similar in saturated clays and satsdotone. 3. The influence of tempera-
ture on the velocity is stronger in mcks saturated with naphta. than in dry samples
of those saturated with mineraliznd water. Orig. art. her: 7 figures.

TITLE; Symmetry group of the hydrogen molecular ion (a system,orith separable vexi-
ables)
SOME: Zh eksper i teor fiz, v. 51, no. 6, 1966, ~573-1879
TOPIC TAGS: hydrogen ion, molecular structure, molecular property, group theory
ABSTRACT: The authors present another example of a,?bysical nyotem where the complete
symmetry group does not reduce to purely geometrical transformations. Such a system
is a molecular hydrogen ion or, in more general form, any systerm consisting of an
electron moving in the field of two differently charged Coulomb eenters. It is shown
that %uch a system has a symmetry group which is higher than geometric, because it
does not obey the Neumann-Wigner theorem, which forbids the cron3ing of tervs having
the same symmetry. It is shown that in the case of the hydrogen molecular ion the
violation of the Neumann-Wigner theorem is only apparent and is related to the circum-
stanco that the geometrical symmetry group does not exhaust the antire symznetry which j
the system possesses., The synnetry group so optained has the farm S02 0 S02 0 02,
with the S02 groups cooresponding to the coordinates of the ellij)tical system in
which the variables became separable. The obtalned group turns out to be idder than

sintering of briquet--'.-.es of metallic vanadium and vanadium
trioxide. The samples were heated at 1 400 OC for 60
to 76 hours. X-ray analysis was carried out and the
results are given in tho table. Samples VO 0-71 :,nd
VO 1.3 were two-phased. A relation between the lattice
parameter and composition was observed only in 'he interval

TEXT : The object of thi-s investi!p-..'Lon was to verify the re-

to obtain more precise information. Carbide specimens of var-

der mixtures of vanadium hydride and spectroscopically pure
graphite in a high frequency induction vacuum furnace at 1600 -

hours at a hydrogen pressure of 1 atm at 8500. The lattice
parameter of the original metal was 3:620 kX, which indicated
a low oxygen content ( < 0.04 at.%); this was also confirmed
by the high strength of the material. Sintering of the car-
bides was carried out for 40 - 70 hours with 2 - 3 intermediate
re-briquetting operations. The compounds were cooled in the
furnace for approximately 30 minutes. X"ray control was carried
out after each operation. The attainment of equiltbrium In the
system was judZed by the constancy of the lattice parameters
and by t1je sharpness of the lines obtained in the X-ray pictures.
The X-ray investigation was carried out in a Cr KX irradial'.-ion
in a Debye Carnera of 143.3 mm diameter. The experimental error
in the determination of lattice periods did not exceed C.001 U.
The density o! the compounds was measured in vacuum by the pic-
nometric method, using kerosene and decalin as the liquid re-
agents. The errors in the density determinations were approx-
imately 0.7%. The analysis of the carbides for vanadium content
was carried out by a volumetric method, and the total and free

constants of the phase components from NbSi 0.15 to Nbsi 0.55 were identical.
The alloys with the stoichiometric composition of Nb 5 SiAand NbSi 2 were
monophase. NbS12 was hexagonal (a - 4.785-kX, c - 6.58 kX), a-Nb 5Si3 was
tetragonal (a - 11-84 kX, c a 6-54 kX). NbSi 0.50-NbSi 0.80 the alloys

(2) slightly solid solution of Si in Nb. NbSio.6o' NbSi o.621 NbSi o.64 and
NbSi 0.66 are monophabe. The identity periods of all latt.-I-cec practically
coincide. By adding -2~4 carbon black or NbO (related to "V0 02) to
Nt-Si mixtures y-Nb 5Si3 and the phase component Nb-Si-C(O) were obtained.

ABSTRACT& The electric resistivity or carbidb p4ases of tant4lum vas measured over
a Wide range of c 31tions (TACO.21-Taco 9~ #,#A temperatures (80-15000K) on Sam-
ples prepared by alater1mg in &'Yacuum OC wt 5 x W5 mm, cooling rapidly to
r temperatw-s, and annealing. On the basis of the esta obtainedo resistivity
islotheran (see FIX6, I' ) and polytherme for 15 carbides of various compositions were
platted. It Is apparent that the *IWric condnativity of Us phase compone-"ts of
the tantal=rcarbon syA= depends substantially on their composition (the carbon
content being a majoe factor) and temperature. Me data indicato that the cirbide
